Description

Technical Field

[0001] The present invention relates to the technical field of water pump equipment in power plants, namely an audible and visual alarm for detecting water leakage in power plant equipment. Background Art

[0002] During the operation of a power plant, equipment inspection is one of the most important daily tasks for operators. When water pump equipment operates for a long time, water leakage is likely to occur. However, it is even more important to be able to detect water leakage in water pump equipment and valves in a timely manner. When inspecting such equipment, the inspector needs to walk near the water pump and other equipment and carefully check every corner of the equipment and the ground to confirm whether there is water leakage. In some cases (when the light is weak at the equipment location), water leakage is not easy to detect. In addition, due to the limitation of the on-site inspection frequency, it is impossible to detect a small amount of water leakage in equipment in a timely manner. Summary of the Invention

[0003] The present invention provides an audible and visual alarm for detecting water leakage in power plant equipment, which is used to timely detect water leakage in water pump equipment during long-term operation. It can timely remind power plant personnel of the water leakage problem of the equipment, save labor costs, and timely remind power plant operators of the equipment water leakage problem so that the water leakage point can be processed in a timely manner.

[0004] The technical solution of the present invention: The audible and visual alarm for detecting water leakage in power plant equipment is characterized by consisting of two parts, namely a detection part for detecting water leakage and an alarm part after detecting water leakage; Detection part: Two sensor probes are 0.5 cm away from the ground, and the distance between the two sensor probes is 15 cm. They are firmly fixed on the ground with suction cups respectively; The alarm part is composed of a triode amplifier circuit, a speaker SP1, and a light-emitting diode LD1.

[0005] Advantages of the present invention: Only need to place multiple groups of sensor probes on the ground, and the alarm part can be placed within the visible range of the camera or human eyes, which is convenient for installation.

[0006] 2. Use audible and visual alarms when detecting water leakage in equipment to assist inspectors in checking for water leakage in equipment, improve work efficiency, save time costs, facilitate operators' inspections, and save time for inspection work.

[0007] 3. Avoid the situation where inspectors cannot detect water leakage in equipment in a timely manner due to weak light or other reasons.

[0008] 4. Even if not on-site, the water leakage in equipment can be detected in a timely manner through the monitoring camera.

[0009] The present invention will be further described below in conjunction with the accompanying drawings: Brief Description of the Drawings

[0010] Figure 1This is the structural schematic diagram of the present invention.

[0011] Figure 2 This is the circuit control schematic diagram of the present invention. Detailed implementation manners

[0012] Refer to Figure 1 、 2 The component names are as follows: sensor probe 1, power supply indicator light 2, battery power supply 3, suction cup 4, triode Q1, triode Q2, triode Q3, speaker SP1, and light-emitting diode LD1.

[0013] Refer to Figure 1 The acoustic-optic alarm device for detecting water leakage in power plant equipment consists of two parts, namely, the detection part for detecting water leakage and the alarm part after detecting water leakage. Detection part: Two sensor probes 1 are placed 0.5 cm above the ground, and the distance between the two sensor probes 1 is 15 cm. They are firmly fixed to the ground with suction cups 4 respectively. The outer dimension of the sensor probe 1, the size of the suction cup 4 below the sensor is a plastic suction cup with a diameter of 2 cm. The sensor probe 1 made of copper rod is installed above the suction cup 4. The diameter of the sensor probe 1 is 0.2 cm and the length is 2 cm. The plastic suction cup and the sensor probe 1 made of copper rod are both corrosion-resistant. The distance from the lowest conductive part of the two sensor probes 1 to the ground is 0.5 cm. The alarm part is composed of a triode amplifier circuit, a speaker SP1, and a light-emitting diode LD1 connected in parallel.

[0014] Taking the installation location as an example, multiple groups of installation locations of the sensor probes 1 are set, and the distance between two sensor probes 1 in each group is 15 cm. The distance between each group of sensor probes 1 is not less than 30 cm (a single acoustic-optic alarm device can have multiple groups of sensor probes 1 working simultaneously without mutual interference).

[0015] Refer to Figure 1 、 2 The design principle is that when the equipment leaks water, the signals collected by the sensors are amplified by multiple stages of triodes Q1, Q2, and Q3 and then sent to the speaker SP1 and the light-emitting diode LD1.

[0016] The material of the installed probe is a copper rod, which is 0.5 cm from the ground. The wire connection is sealed with a plastic tube to play a protective role. The distance between the two sensor probes 1 is 15 cm, all to avoid false alarms caused by a small amount of condensed water on the water pipe wall dripping to the ground due to the too cold cooling water temperature. The size of the suction cup 4 is 2 cm in diameter to be more conveniently placed in a narrow space and firmly adsorbed on the ground. The diameter of the sensor probe 1 is 0.2 cm to have sufficient contact area with water to more sensitively detect the water leakage signal while maintaining good electrical conductivity. The circuit protection plastic shell prevents factors such as environmental humidity from affecting the service life of the device. The light-emitting diode LD1 is protected by a glass shell, which is easy to observe, small in size, easy to place at any position, and can prevent factors such as environmental humidity from affecting the service life of the diode. This design uses a 4.5V power supply to ensure the power supply reliability of the alarm device, and uses multiple triodes Q1, Q2, Q3. In this way, the detection signal is amplified in multiple stages, enabling the water leakage signal to be more sensitively fed back to the alarm unit and enabling the water leakage situation to be detected more quickly.

[0017] The above description is only the specific implementation manner of the present invention, and various examples do not constitute a limitation to the essence of the present invention.
